Right now, for maybe a month back, they've been on a pre-made from a brand called 'HobbyFirst' mix which I am just google translating for you:
Crushed Corn, Crushed Wheat, Sorghum, Crushed Barley, High Carbonated Shellfish, Corn, Soy, Wheat, Split Peas, Buckwheat, Calcium Carbonate, Rapeseed...
One of my girls have laid two eggs with no shell. I have sea shells but doesn't seem to help, can I give them reptile calcium? I have two different kinds.
